Title: Shortening of laser pulse with a self modulated phase at the focus of a lens.

Abstract

We found that, at the focus of a chromatic lens, a laser pulse with a self-modulated phase can be shortened due to the radial dependence of the group delay imposed by the lens. Normally, this group delay stretches a short pulse into a long pulse by spreading the arrival time of the pulse at the focus. However, for a pulse with a self-modulated phase, it causes the fields with different phases to overlap, thus resulting in destructive interference that shortens the pulse.

  • Pulse shortening from 22 to 18 fs and spectral-broadening from 41 to 108 nm were observed in a self-mode-locked Ti:sapphire laser when the pulse train showed amplitude modulation with a period ranging from 150 to 400 ns. The mechanism of pulse-train amplitude modulation is attributed to the high-order transverse modes in the laser cavity. {copyright} 1997 Optical Society of America
  • A laser pulse with a power of {similar_to}3 TW and a duration of 1 ps has been focused onto a gas. Ultrahigh-gradient electron acceleration has been observed in the laser-produced plasma with a density of {similar_to}10{sup 19} cm{sup --3} when injecting 1 MeV/{ital c} electrons. The simulation of the laser-plasma interaction revealed the existence of ultrahigh-gradient wake fields excited due to self-modulation of the laser pulse and its electron acceleration, consistent with the experimental results.
  • The effect of asymmetric laser pulses on plasma wave excitation in a self-modulated laser wakefield accelerator is examined. Laser pulse shape and frequency chirp asymmetries, controlled experimentally in the laser system through a grating pair compressor, are shown to strongly enhance measured electron yields for certain asymmetries. It is shown analytically that a positive (negative) frequency chirp enhances (suppresses) the growth rate of the Raman forward scattering and near-forward Raman sidescatter instabilities, but is of minimal importance for the experimental parameters. Temporal laser pulse shapes with fast rise times (< plasma period) are shown to generate larger wakes (compared tomore » slow rise time pulses) which seed the growth of the plasma wave, resulting in enhanced electron yield.« less
  • Background and Purpose: This phase 2 study investigated the efficacy and safety of preoperative intensity modulated radiation therapy with a simultaneous integrated boost (IMRT-SIB) without dose escalation, concomitant with standard capecitabine chemotherapy in locally advanced rectal cancer. Methods and Materials: Between January 2014 and March 2015, 51 patients with operable stage II-III rectal adenocarcinoma received preoperative IMRT with pelvic dose of 41.8 Gy and simultaneously delivered 46.2 Gy to T2/3 and 48.4 Gy to T4 tumor in 22 fractions, concomitant with capecitabine, 825 mg/m{sup 2}/12 hours, including weekends. The primary endpoint was pathologic complete response (pCR). Results: Fifty patients completed preoperative treatment according to themore » protocol, and 47 underwent surgical resection. The sphincter preservation rate for the low rectal tumors was 62%, and the resection margins were free in all but 1 patient. Decrease in tumor and nodal stage was observed in 32 (68%) and 39 (83%) patients, respectively, with pCR achieved in 12 (25.5%) patients. There were only 2 G ≥ 3 acute toxicities, with infectious enterocolitis in 1 patient and dermatitis over the sacral area caused by the bolus effect of the treatment table in the second patient. Conclusions: Preoperative IMRT-SIB without dose escalation is well tolerated, with a low acute toxicity profile, and can achieve a high rate of pCR and downstaging.« less
  • Pulse propagation in a photodissociative iodine-laser amplifier is investigated both experimentally and numerically. Pulse reshaping and shortening occur in agreement with theory. It is found that pulse shortening by gain saturation is impractical for subnanosecond pulses.
